HNLMS O 1
O 1 was a Holland 7P patrol submarine of the Royal Netherlands Navy. The ship was built by the De Schelde shipyard in Flushing and was the first submarine in the Dutch navy. It had a diving depth of 25 metres.
Service history
The submarine was laid down in Flushing at the shipyard of De Schelde under the name of Luctor et Emergo on 1 June 1904, as it was not yet certain the Dutch navy would purchase the ship. The design came from the American company Holland Torpedo Boat Co. The engineer Marly Hai was sent to the shipyard to assist in the construction of the submarine. The launch took place on 8 July 1905.
A series of trials and tests were held that were overseen by committee appointed by the Ministry of Defence. The committee was not satisfied after the first series of tests but after the second series of tests the ship was purchased by the navy for 430,000 Dutch Guilders.
On 21 December 1906 the ship was commissioned in the navy as Onderzeese boot 1 (Submarine 1); it is uncertain at which point the ship was renamed to O 1.
